  The 
  laterally 
  compressed 
  form 
  of 
  this 
  species 
  serves 
  to 
  distinguish 
  

   it 
  from 
  all 
  other 
  Belemnites. 
  The 
  alveolar 
  cavity 
  in 
  our 
  specimen 
  

   is 
  rather 
  more 
  elliptical 
  than 
  round, 
  as 
  is 
  usually 
  the 
  case 
  ; 
  but 
  this 
  

   may 
  be 
  due 
  to 
  weathering. 
  The 
  longitudinal 
  impressions 
  are 
  distinct 
  

   on 
  both 
  sides.

  There 
  are 
  several 
  specimens 
  to 
  represent 
  this 
  very 
  variable 
  shell 
  ; 
  

   but 
  the 
  specific 
  character 
  is 
  unmistakable 
  in 
  all, 
  that 
  of 
  the 
  smooth 
  

   median 
  space 
  which 
  traverses 
  the 
  dorsal 
  region 
  of 
  both 
  valves.
